(WTOC) - Thereâs no doubt people have been anxiously waiting for the interchange and roundabout to finally open at Belfast Keller Road and county leaders are certainly no exception. Many people have been driving by and slowing down to admire the project and itâs one county leaders say itâs been a long time coming.
